WALTER L. SCHULTZ, OF CHICAGO, ILLINOIS.

REINFORCED-CONCRETE FLOOR CONSTRUCTION.

To all whom it may concern Be it known that I, \VAL'rnR L. SCHULTZ, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Reinforced-Concrete Floor Construction, of which the following is a complete specification.

The main objects of this invention are to provide a reinforced concrete floor construction which will be very rigid and of great strength; to provide a reinforced concrete floor construction which is simple and easy to assemble; and to provide a reinforced concrete construction in which the tension rods are supported intermediate their ends by means to prevent their turning.

A specific embodiment of the invention is illustrated in the accompanying drawings, in which:

Figure l is a fragmentary section of a concrete floor construction showing one of the tension rods and the supporters therefor. Fig. 2 is an enlarged transverse section of the rod, with one of the supporters in end elevation. Fig. 3 is an enlarged fragmentary plan view of the rod and one of its supporters. Fig. 4 is a transverse section of the rod showing in end elevation a modified form of the supporter. Fig. 5 is a plan view of the construction shown in Fig. 4.

In the construction shown, the sub-fioor 1 is constructed of wood, metal, or any other desired material, and provides a base or support for the reinforced concrete. Mounted on the sub-floor 1 at the proper distances apart are the supporters 2 for the tension rod 3. Said supporters, as shown more clearly in Figs. 1 to 3 inclusive, are formed of Z shaped plates or sheets of metal which are adapted to rest on edge on the sub-floor l. The end pieces 4 and the diagonal connecting piece 5 of the sup porters are provided with alined V shaped notches or seats 6 in their upper edges in which the rod 3 seats, and which serve to hold the rod from turning.

In the construction shown in Figs. 4 and 5 the supporter 7 is provided with alined Specification of Letters Patent. 7

apertures or seats 8 in its end pieces 4 and connecting piece 5, near the tops thereof, and through which the rod 8 extends. The rods 3 may be placed at any desired distance apart, and the supporters 2or 7 may be placed at proper intervals throughout the lengths of the rods to prevent the rods from sagging or turning. The structure thus formed is then embedded in the concrete 9.

While I have shown but one specific embodiment of the invention it will be understood that various details of the construction shown may be varied or omitted without departing from the scope of the claims.

I claim:

1. A reinforced concrete floor construction comprising a tension rod, and a plurality of Z shaped supporters for said rod, each Z shaped supporter to stand on edge and having seats on the upper edges, each supporter being adapted to support the rod at a plurality of seats.

2. A reinforced concrete floor construction comprising a tension rod, and a plurality of Z shaped members adapted to stand on edge and each having seats adjacent to their upper edges adapted to receive the rod and support it at a plurality of seats.

3. A reinforced concrete floor construction comprising a sub-floor, a plurality of Z shaped supporters mounted on edge on said sub-floor and having alined seats in their upper portions, rods extending longitudinally of said supporters, each rod being supported at a plurality of points by said seats.

4. A reinforced concrete construction comprising a plurality of Z shaped supporters adapted to stand on one edge and each having a plurality of alined V shaped seats in the other edge, and a rod adapted to lie in said seats and be supported at a plurality of points by each supporter.

In witness whereof I have hereunto subscribed my name in the presence of two witnesses.
